I'm blaming gfortran:

      program add
      implicit none
      real a,b,s
      read *, a
      print *, ' is ' , int(a)
      stop
      end


(sid_mips-dchroot)jtaylor at gabrielli:~$ ./a.out
-1e99
  is   2147483647

according to https://gcc.gnu.org/onlinedocs/gfortran/INT.html this
should be -2147483648
